Boron-containing compounds, light-emitting materials, and light-emitting devices using the same

Abstract

Provided are: a compound represented by formula (II); a luminescent material containing this compound; and a luminescent element containing this luminescent material. (In formula (II), R1, R2, R3, R4, R5, R6, R7 and R8 are each independently a straight chain or branched chain alkyl group having 1-4 carbon atoms, m values are each independently an integer between 0 and 5, and n values are each independently an integer between 0 and 4.)
